Itti算法和他的文章。Itti提出的显著图模型是一种模拟生物体视觉注意机制的选择性注意模型,比较适合处理自然图像。(Itti algorithms and his article. Itti saliency map model proposed is a simulation of selective attention model organism visual attention mechanism, more suitable for processing natural images.)

matlab中编写的一个计算PI参数的程序，可以自动整定控制系统的PID参数(PID controller caculate)

功率开关器件全桥电路设计，经调试，绝对正确(power_bridges)

pear1.5的安装包，解压到smarty的目录基本就可以使用了。(pear1.5 installation kits, smarty extract the basic directory can use it.)

说明：  cox回归分析的学习总结资料，包括example。PPT(cox regression analysis of the study summary data. PPT)

用于圆形金属波导模式求解，得到特征方程的根，可设定误差范围。(Circular metal waveguide model for solving the characteristic equation has been the root of error range can be set.)

自己编的程序，实现快速傅里叶变化，结果和matlab自带的fft2一样。(Own series of programs, fast Fourier transform, results and matlab native fft2 the same.)

解常微分方程的Matlab程序 字符串ypfun是用以表示f(t, y)的M文件名, tspan=[t0, tfinal]表示自变量初值t0和终值tf y0表示初值向量y0，可选参数options为用odeset设置精度等参数。 输出列向量tout表示节点，输出矩阵yout 表示数值解，每一列对应y的一个分量。若无输出参数，则作出图形。(Solution of ordinary differential equations of the Matlab program is used to indicate ypfun string f (t, y) M-file name, tspan = [t0, tfinal] said that since the variable t0 initial and final values of tf y0, said initial vector y0 , optional parameters to set options for the use of odeset accuracy and other parameters. The output column vector tout that node, the output matrix yout that of numerical analysis, each column corresponds to y of a component. If there are no output parameters, then make a graph.)

说明：  扩频系统中的小实验，具体介绍在文件kuopin_all中有介绍。(spread spectrum system of small experiments, which are detailed in the document kuopin_all were introduced.)
